I have a TRW/Federal power steering pump I'm trying to adapt to my
72 Dart 383 swap. The hose I have on the car has an O-ring fitting and the pump I've adapted has the older flared fitting. I have a hose with the flare, but the end that goes to the steering unit has a smaller fitting than my box. My plan is to cut the O-ring end off and flare it to mach the pump...

Do you guys know the flare/style I need to make this work? I just ordered a flare kit, but I've not used one previously.

Thanks in advance for any help.
